Without traumatic history, spontaneous hemarthrosis of the knee is a relatively rare condition, and there is no report of the diagnosis and treatments in Korea. In this case, magnetic resonance imaging and arthroscopic findings showed hemarthrosis and a lateral meniscus tear. Hemarthrosis of the patient remained after meniscus resection and coagulation; we then, found rupture of the lateral geniculate artery by computed tomography-angiography. We report on a case of successful treatment of spontaneous hemarthrosis with therapeutic embolization with a thorough review of the relevant literatures.

BACKGROUND: It is important to choose effective primers to increase the sensitivity of RT PCR for HCV. It was reported that the use of narrowly spaced primers (NSP) resulted in increased sensitivity of HCV PCR because NSP is more effective than widely spaced primers (WSP) in RT or PCR reaction. It will be useful to compare the merits and demerits of PCR using NSP (NSP-PCR), PCR using WSP (WSP-PCR) and anti-HCV EIA. METHODS: We performed NSP-PCR, WSP-PCR, anti-HCV EIA tests and determined sensitivity and specificity of each method with 36 sera from patients with hepatitis C and 14 sera from patients with diseases other than hepatitis C. RESULTS: The sensitivity and specificity for WSP-PCR were 80.6% and 100%, those for NSP-PCR were 86.1% and 78.6%, and those for anti-HCV EIA were 94.4% and 100%. The concordance rate for anti-HCV EIA and WSP-PCR was 82% and that of anti-HCV EIA and NSP-PCR was 80%. The detection limit of WSP-PCR was up to 10(-1) dilution and that of NSP-PCR was up to 10(-2) dilution. The positive bands of WSP-PCR were strong and large. But those of NSP-PCR were weak and small, so it was not easy to differentiate them from primer dimers sometimes. CONCLUSIONS: WSP-PCR seemed to be better than NSP-PCR for clinical laboratory tests. Anti-HCV EIA appears to be a good screening test for liver disease because of the high sensitivity and specificity.

We present a case of adult onset Still's disease (AOSD) that was misdiagnosed as septic arthritis of the shoulder and knee. A forty-nine-year-old woman was admitted for pain in the left knee. The patient's medical history showed that she had undergone arthroscopic irrigation twice and an open debridement under the diagnosis of septic shoulder at another hospital. The laboratory and joint fluid analysis findings led us to suspect septic knee. Arthroscopic irrigation and antibiotics treatment were performed. At five weeks after discharge, she presented with pain in the same joint, fever, and rash. The symptoms were consistent with Yamaguchi's criteria for AOSD. We started corticosteroid therapy, and clinical remission was achieved. In conclusion, we suggest that AOSD should be considered as a diagnosis of exclusion to avoid misdiagnosis with septic arthritis.

STUDY DESIGN: Prospective, single-center study.PURPOSE: The current trend of operative treatment for adult spinal deformity (ASD) is combined anterior-posterior staged surgery. When anterior surgery was first performed, oblique lumbar interbody fusion (OLIF) was employed; this method became increasing popular. This study aimed to determine the lordosis correction that can be achieved using OLIF and assess whether we can preoperatively predict the lordosis correction angle achieved using OLIF.OVERVIEW OF LITERATURE: Many previous studies on OLIF have shown improved clinical and radiologic outcomes. With the increase in the popularity of OLIF, several surgeons have started using larger cages to attain greater lordosis correction. Moreover, some studies have reported complications of OLIF because of immoderate cage insertion. To our knowledge, this is the first prospective study that attempted to determine whether it is possible to predict the lordosis correction angle achieved with OLIF preoperatively, using fullextension lateral view (FELV).METHODS: Forty-six patients with ASD were enrolled. All the operations were performed by a single surgeon in two stages (first, anterior and second, posterior) with a 1-week interval. Radiological evaluation was performed by comparing the Cobb’s angle of the segmental and regional lordosis obtained using preoperative and postoperative simple radiography (including the FELV) and magnetic resonance imaging (MRI).RESULTS: Regional lordosis (L1–S1) in the whole-spine standing lateral radiograph was −3.03°; however, in the supine lateral MRI, it was 20.92°. The regional lordosis of whole-spine standing lateral and supine lateral (MRI) was significantly different. In the FELV, regional lordosis was 25.72° and that in the postoperative supine lateral (MRI) was 25.02°; these values were not significantly different.CONCLUSIONS: Although OLIF offers many advantages, it alone plays a limited role in ASD treatment. Lordosis correction using OLIF as well as lordosis determined in the FELV was possible. Hence, our results suggest that FELV can help predict the lordosis correction angle preoperatively and thus aid the selection of the appropriate technique in the second staged operation.

STUDY DESIGN: Retrospective study. OBJECTIVES: We analyzed the clinical results of thoracic myelopathy caused by ossification of yellow ligament (OYL) and to explore prognostic factors after surgical treatment. SUMMARY OF LITERATURE REVIEW: Thoracic myelopathy due to OYL is difficult to treat; surgery is considered as treatment of choice. However, studies of the clinical results and prognostic factors are few due to its rare presentation. MATERIALS AND METHODS: Twenty six patients who had surgery for thoracic myelopathy caused by OYL were evaluated from February 2002 to April 2012. We describe the analysis of the clinical results after surgery and prognostic factors. RESULTS: Modified Japanese orthopedic association (JOA) score was recorded in all patients by 5.7+/-1.3 points (range, 2-9 points) preoperatively, 7.8+/-1.7 points (range, 4-10 points) postoperatively, and 8.4+/-2.1 points (range, 5-11 points) at final follow-up. Hirabayashi recovery rate was recorded by 60.2+/-20.2% (range, 45.5-72.0%) postoperatively, 64.5+/-17.3% (range, 50.2-75.1%) at final follow-up. The Visual Analogue Scale (VAS) score was also improved by 7.6+/-1.8 points (range, 7-10 points) preoperatively, 4.5+/-1.3 points (range, 3-6 points) postoperatively, and 3.8+/-1.6 points (range, 2-5 points) at final follow-up. Both modified JOA score and VAS score improved significantly (p<0.05). In prognostic factor analysis, OYL type on CT axial image, duration of symptom, and preoperative severity of myelopathy was significant (p<0.05). CONCLUSION: We showed the effectiveness of surgery on patients who suffer from thoracic myelopathy caused by OYL and that OYL type identified by CT axial image, duration of symptom, and preoperative severity of myelopathy were significant prognostic factors.

STUDY DESIGN: A retrospective-based study. OBJECTIVES: To evaluate the usefulness of iliac screws in the surgical correction of sagittal imbalance by changes of spinopelvic parameters. SUMMARY OF LITERATURE REVIEW: Although reports exist regarding the fusion rates on lumbosacral fusion by iliac screws, no previous studies address the issue of changes of spinopelvic parameters on surgical correction of sagittal imbalance by iliac screws. MATERIALS AND METHODS: We analyzed a total of 23 patients who were operated on by pedicle subtraction osteotomy and posterior fusion on sagittal imbalance. Patients were divided into two groups: 1) non-iliac screw fixation and; 2) iliac screw fixation. The two groups were compared during the preoperative and postoperative stages, and the last follow-up spinopelvic parameters of two groups. RESULTS: Spinopelvic parameters, except for pelvic incidence, were corrected after surgery; some corrected values of spinopelvic parameters were lost during follow-up. There was a statistically significant difference in the last follow-up period between lumbar lordosis and pelvic tilt. Values of postoperative lumbar lordosis and pelvic tilt was similar to each other; however, during the follow-up period corrected values of spinopelvic parameters of non-iliac screw fixation group were more lost. There were no statistically significant changes in postoperative and last follow-up sacral slope and pelvic incidence. CONCLUSIONS: Sagittal imbalance could be corrected by pedicle subtraction osteotomy, and corrected values of lumbar lordosis and pelvic tilt of iliac screw fixation group could be maintained well compared to non-iliac screw fixation. Iliac screw fixation could be useful for maintenance of corrected values of spinopelvic parameters in surgical correction of sagittal imbalance.

PURPOSE: To evaluate the efficacy and safety of silodosin 8 mg once daily in a 12-week treatment of subjects with severe lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A total of 100 subjects from 10 urology centers in Korea were included in this study. The inclusion criteria were as follows: age > or =50 years, International Prostate Symptom Score (IPSS) > or =20, quality of life (QoL) score > or =3, urine volume > or =120 mL and maximal urinary flow rate (Qmax) <15 mL/s, and postvoid residual volume (PVR) <100 mL. We assessed the improvement of LUTS with change in IPSS, QoL score, Qmax, PVR, and adverse events at baseline and 4 and 12 weeks after treatment with silodosin 8 mg once daily. RESULTS: The IPSS values were 23.27+/-3.34, 15.89+/-6.26, and 13.80+/-6.31 at baseline, 4, and 12 weeks, respectively, with significant improvements (p<0.0001, p=0.0214, respectively). QoL scores were 4.44+/-0.85, 3.38+/-1.20, and 3.04+/-1.20 at baseline, 4, and 12 weeks, respectively, and the differences were statistically significant (p<0.0001). There was a significant difference in Qmax between baseline and 12 weeks (p<0.0001) but not in PVR (p=0.9404) during the clinical trial. The most frequent adverse event in this study was ejaculation failure with 13 cases. However, no subject dropped out because of ejaculation failure, and in 12 of the 13 cases it was fully resolved without further treatment. CONCLUSIONS: Silodosin 8 mg once daily may be effective and safe in Korean patients with severe LUTS associated with BPH.

Gastric glomus tumors are rare submucosal lesions that originate from the modified smooth muscle cells of the glomus body. They usually present as a submucosal tumor on endoscopy and a heterogeneous hypoechoic tumor in the third or fourth sonographic layer of the gastric wall on endoscopic ultrasonography. So they are often confused with other submucosal tumors such as gastrointestinal stromal tumor, schwannoma, and leiomyoma. Immunohistochemistry helps in differentiating glomus tumors from other submucosal tumors. The treatment of choice for these tumors is complete surgical resection. Most of the gastric glomus tumors are essentially benign in nature, so preoperative recognition of this lesion may spare the patient a more extensive resection. Herein, we present three cases of gastric submucosal tumor that were treated by a laparoscopic wedge resection and confirmed as glomus tumor on final pathology.

Peptic ulcer which extend beyond the serosa of the bowel wall may not perforate freely into the peritoneal cavity but instead penetrate adjacent structures (confined perforation). It has been reported that the frequency of penetration of peptic ulcer has been estimated around 20 percent in patients undergoing laparotomy for peptic ulcers. A 46-year- old male was admitted with chief complaint of hematemesis. Endoscopic examination revealed submucosal tumor like lesion with central ulcer and active bleeding which was located at the upper body, posterior wall of the stomach. Angiography demonstrated hypervascular tumor like lesion supplied by left gastric artery and short gastric branches of splenic artery. Postoperative biopsies showed inflammatory cell infiltration at the typical ulcer base and no evidence of malignancy. There was loss of acinus structure and fibrous adhesion with omentum at the pancreas. We report a case of gastric ulcer penetrating into pancreas, spleen with hypervascular nature with brief review of literatures.

STUDY DESIGN: Retrospective study. OBJECTIVES: As we analyze the incidence and the risk factor for proximal junctional problem after surgical treatment of lumbar degenerative sagittal imbalance, we want to contribute to reducing the junctional problem of surgical treatment of lumbar degenerative sagittal imbalance. SUMMARY OF LITERATURE REVIEW: Surgical treatment of degenerative spinal deformity has increased. Rigid fixation was a risk factor for degenerative change of adjacent segment and failure, and it remains a big challenge for the junctional problem of surgical treatment. However, research on the correlation with risk factors is rare. MATERIALS AND METHODS: Forty four patients (mean age 66.5; range, 50-74) who had surgery due to lumbar degenerative sagittal imbalance were evaluated by the risk factor associated with junctional problems from January, 2005 to December, 2011. The risk factors were analyzed by surgical factor (proximal fusion level, using iliac screw, correction or undercorrection of lumbar lordosis compared with pelvic incidence) and patient factor (age, bone marrow density, body mass index). RESULTS: Junctional problems occurred in 18 patients (41%) out of 44 patients. Among these problems, there were 10 cases of fractures, 8 cases of junctional kyphosis, and 4 cases of proximal screw pull out. . Among the risk factors, only the correction or undercorrection of lumbar lordosis compared with pelvic incidence in surgical factor was statistically significant. Other surgical factors and patient factors were not statistically significant. CONCLUSIONS: Junctional problems after a surgical treatment of lumbar degenerative sagittal imbalance were common. However, we could not know the exact risk factor of junctional problems except the degree of correction of lumbar lordosis compared with pelvic incidence, because most of the risk factors were not statistically significant. So, further evaluations of the risk factor of lumbar degenerative sagittal imbalance are required.
